De-Pivot and Value Types
Contributor II
Hi guys,
I'm working with the De-Pivot operator to transform some data, currently in one line to different lines.
Just up front, I'm working with 5.3.015 open scource.
The original data looks like:
The data in Value_Month1 is of the "real" type and the data Value_Month2 is a "numeric" attribute.
I use De-Pivot to transform it into
An error message is delivered quoting that the two types are not compatible so de-pivotisation can't be done.
Is it a bug? Maybe it is already fixed, I don't know?
I got a work around using first NumericToNominal and then NominalToNumeric to get the type of Value_Month1 attribute from "real" to "numeric"
But still I think it is odd that the two types "numeric" and "real" are compatible everywhere else but while using De-Pivot.
And it also arose the question: What are the differences between "real" and "numeric"? Why are both in use?
Haven't found anything in the Manual so far.
Cheers
Garf

1. Same problem occures between "real" and "integer"
2. Is there some kind of NumericToReal or IntegerToNumeric, ... operator? Just found RealToInteger which might not be sufficient for all possible tasks.
